Corsair TR3X6G1600C8D Dominator 6 GB 3 x 2 GB PC3-12800 1600MHz 240-Pin DDR3 which is 8-8-8-24 and 1.65v, which I spent $243 for in 2010. It has served me well, however I am having instances when I am hitting 85% usage with apps/VM's and just ordered this:

I am hoping I don't see any decrease in performance, and I don't overclock so I think I will be fine. But I am looking for some simple type of memory benchmark, kind of like CrystalDiskMark but just for RAM, anyone have any good ones, or want to provide any feedback on my decision?

As far as I know, the difference in cheap and expensive RAM is almost none. I could be wrong though.

I don't believe you will ever be bottlenecked by RAM, so there's not really any reason to spend a lot of money on some. I'm sure your new stuff will be almost identical to your old stuff, so there's probably not too much to worry about in regards to benchmarks.

Well SiSoft hard-locked my machine once I started the tests.. which never happens.. plus it's just one big advertisement to sell hardware, not like it used to be.. and PCMark won't let you run a memory test unless you purchase.. Let me check out MaxxMEM

Edit: So MaxxMEM screenshot looks like what I am looking for, sadly it hard locked my system also when starting just the GUI. Must be a Windows 8 issue.
